Hi

9x - 3(2+4x) = 9x-3(2)-3(4x) = 9x-6-12x = 9x-12x-6
9x - 3(2+4x) = -3x-6

Answer: -3x-6

Name a decimal between 0.4 and 0.5
Aliun [14]

To find a number between both decimals, what you can do is take the average of both numbers.

We have then:

average = \frac{0.4+0.5}{2}

Rewriting we have:

average = \frac{0.9}{2} \\average = 0.45

Therefore, the decimal obtained is a number between 0.4 and 0.5

Answer:

a decimal between 0.4 and 0.5 is:

average = 0.45

P is a rectangle with a length 40 cm and width x cm
TiliK225 [7]
The first thing we must do for this case is to look for the area of each rectangle.
 We have then:
 A1 = (40) * (x)
 A2 = (1.25 * 40) * (y)
 Then, we have the following relationship between areas:
 "the area of Q is 10% less than the area of p"
 A2 = 0.9 * A1
 Substituting values we have:
 (1.25 * 40) * (y) = 0.9 * ((40) * (x))
 We rewrite:
 50y = 36x
 The relationship x: y is:
 x / y = (50) / (36)
 Simplifying:
 x / y = (25) / (18)
 Answer:
 
the ratio of x:y is:
 
25:18

When Gabriella runs the 400 meter dash, her finishing times are normally distributed with a mean of 79 seconds and a standard de
kupik [55]

Answer:

(78, 80)

Step-by-step explanation:

Given a normal distribution :

Mean = 79 seconds

Standard deviation = 0.5 seconds

Using the empirical rule :

95% of her finishing times :

According to the empirical rule, 95% represents 2 standard deviations from the mean that is ± 2 standard deviations from the mean score or value.

Hence ;

The interval will be defined as ;

Mean ± 2(standard deviation)

79 ± 2(0.5)

79 ± 1

(79 - 1) ; (79 + 1)

78 ; 80

KatRina [158]

Step-by-step explanation:

30% of the money was equal to 51

so:

\frac{30}{100}  =  \frac{51}{x}  \\  \\ x =  \frac{5100}{30}  =  \frac{510}{3}  = 170
